Federal Highway Administration

The FHWA's mission is to improve mobility on our Nation's highways through national leadership, innovation, and program delivery. One of the agency's key roles is to be an innovator for a better future. Toward this end, FHWA provides leadership, expertise, and resources to continually improve the quality of the highway system and its intermodal connections. Cooperating with States and other partners, the agency coordinates Federal highway programs and conducts supporting research in highway safety, pavement and structures, congestion relief, planning, and the environment. Among the agency's major highway programs are the Federal-Aid Highway Program, which provides financial assistance to States to construct and improve the National Highway System, urban and rural roads, and bridges, and the Federal Lands Highway Program, which provides access to and within national forests, national parks, Indian reservations, and other public lands.

Funding Trends FY 2007–2009

Figure 6 shows FHWA RD&T funding for the 3-year period covered by this report. Funding details are in Appendix A.

The FHWA's FY 2009 request is up 4 percent compared to actual FY 2007 funding, from $554 to $577 million, reflecting the funding levels authorized in SAFETEA-LU. The FY 2009 request is up $32 million (6 percent) from enacted FY 2008 funding of $545 million. Of the total request for FY 2009, just $241.5 million (42 percent) is under FHWA stewardship: $196.4 million for Surface Transportation Research, Development, and Deployment (STRDD); $26.7 million for Training and Education; and $18.4 million for Administrative Expenses. RITA administers the ITS Program ($110 million) and the University Transportation Centers ($69.7 million), which together account for 31 percent of FHWA's FY 2009 RD&T request. Another $156.2 million, or 27 percent, reflects the share of State Planning and Research apportionments that States must allocate for RD&T.

Support for DOT Goals

Figure 7 shows how FHWA's FY 2009 RD&T request will support DOT goals. The request will support all goals, with an emphasis on reduced congestion (75 percent) and safety (13 percent). Other supported goals include environmental stewardship (6 percent); organizational excellence (5 percent); and global connectivity (1 percent). Less than 1 percent of the RD&T budget will address security, preparedness, and response. Additional details are in Appendix B.
